Detailed ways

In order to understand the above objects, features and advantages of the present application more clearly, the solution of the present application will be further described below. It should be noted that, as long as there is no conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

In order to improve the current sound effect adjustment control method for in-car music playback, there are few tuning interfaces and the tuning setting effect is not ideal, which will cause technical problems such as poor user experience. This embodiment provides a sound playback control method, as shown in Figure 1. The method includes:

Step 101: Obtain the user's tuning configuration information for different channels.

Different from the left channel and the right channel, the different channels in this embodiment may be channels in different areas in the car, and the tuning configuration information of these different channels may include: Mute configuration, gain configuration, delay configuration, etc.

For example, the area in the car in this embodiment can be the area in the vehicle cockpit, and the different sound channels can be the sound channels in different areas in the cockpit, such as the center channel, the left front door channel, the right front door channel, Left rear door channel, right rear door channel, left surround channel, right surround channel, left front 3D channel, right front 3D channel, left rear 3D channel, right rear 3D channel, etc.

The execution subject of this embodiment may be a sound playback control device or device, which may be configured on the vehicle end. In this embodiment, more tuning interfaces can be opened on the operation interface of the vehicle system, which may specifically include: muting or canceling muting of each channel, etc., resulting in a higher degree of freedom in audio control; Gain settings, the gain can be adjusted arbitrarily within a range, and the settings can be reset to default values, etc., to finely define the sound quality that the user likes; delay settings for each channel, the delay can be adjusted arbitrarily within a range , and can reset the settings to default values, etc. You can control the sound field and sound image of the entire vehicle, and adjust the width, depth or height of the sound field.

In practical applications, users can configure the corresponding mute information, and/or gain information, and /or delayed information etc., which can greatly increase the user's freedom in tuning. Multiple sound channels in different areas in the car can be set separately, and the vehicle sound effects can be customized based on the music playback environment of the areas in the car. The resulting sound effect parameter values are more Suitable for car music playback.

Step 102: Perform digital signal tuning processing on the media stream by calling the control interface based on the sound effect parameter values corresponding to the tuning configuration information of different channels in the sound effect algorithm library.

Among them, the media stream after tuning processing can be used for sound playback.

The sound effect algorithm library may contain sound effect parameter values corresponding to different tuning configuration information. In this embodiment, the user's tuning configuration information for different channels according to the area in the car can be obtained from the sound effect algorithm library. sound effect parameter values.

For example, as shown in Figure 2, in the car head unit (HU) system, the user can make sound effect adjustments on the user interface (UI) of the tuning, and mute the different channels in the car according to the area in the car. , and/or gain configuration, and/or delay configuration, etc., the vehicle system will control the call of the corresponding tuning interface, and send the tuning configuration information to the Digital Signal Processing (DSP) module, and then through The control interface controls the corresponding parameter values of the algorithm library in the DSP in real time to achieve real-time tuning. At the same time, the media stream of the sound (audio broadcast sound, or song sound, or video sound, etc.) is also connected to the DSP module through the media interface. In the DSP module, the sound effect parameter values corresponding to the current configuration information (mute configuration of different channels, and/or gain configuration, and/or delay configuration, etc.) in the sound effect algorithm library are obtained, and then based on the obtained sound effect parameters The value is to perform digital signal tuning processing on the accessed media stream, so that the media stream can be processed by a real-time tuning algorithm. Finally, the tuned media stream is emitted through a power amplifier and a speaker, and then the sound is played and perceived by the user.

Compared with the current way of setting the left channel and right channel only through an equalizer, this embodiment can open the tuning interface of multiple channels in different areas in the car to the user, and can fully consider the different conditions in the car. Sound effect parameter settings for regional sound playback. Specifically, during car music playback, users can control the muting of any channel and adjust the sound quality, sound field and sound image of the entire car. It can greatly increase the user's freedom in tuning. Multiple sound channels in different areas in the car can be set separately, and the vehicle sound effects can be customized based on the music playback environment of the area in the car. The obtained sound effect parameter values are more suitable for the vehicle. Music playback can effectively improve the user's experience of listening to music in the car, thus improving the user's car experience.

Further, as a refinement and expansion of the above embodiment, in order to completely explain the specific implementation process of the method of this embodiment, this embodiment provides a specific method as shown in Figure 3, which method includes:

Step 201: Obtain the current driving characteristics of the vehicle.

For this embodiment, in order to help the user quickly set the tuning parameters that match the current driving scene, the corresponding tuning setting information may be recommended before the user sets the tuning parameters. Specifically, based on the current driving characteristics of the vehicle, the historical configuration information of different audio channels selected by the user in similar historical driving scenes can be obtained to recommend information. Specifically, the process shown in steps 201 to 203 can be executed.

Among them, driving characteristics include: time information, driving information, vehicle status information, vehicle location information and vehicle environment information.

Optionally, the time information may include: current time, today's date type, and the driving time of the current trip. For example, the current time may specifically include: the current year, month, day (the day of the month), hour, and minute. The specific date types of today can include: working days, holidays, weekends, etc. The elapsed driving time of the current trip can be the driving time from power-on to the current moment of the current trip. This data reflects the user's driving fatigue to a certain extent.

The driving information may include: the average speed of the vehicle within a certain period of time before the current time, the number of times the vehicle's accelerator pedal is pressed within a certain period of time before the current time, the number of rapid accelerations of the vehicle within a certain period of time before the current time, The number of rapid decelerations of the vehicle within a certain period of time before the current time. For example, the average speed of the vehicle within a certain period of time before the current time can be the average speed of the vehicle in the previous 5 minutes starting from the current time. The number of accelerator pedal depressions of the vehicle within a certain period of time before the current time may be the number of accelerator pedal depressions of the vehicle within the first 10 minutes starting from the current time. The number of rapid accelerations of the vehicle within a certain period of time before the current time may be the number of times the vehicle acceleration is greater than a certain threshold in the first 10 minutes starting from the current time. The number of rapid decelerations of the vehicle within a certain period of time before the current time can be the number of times the vehicle acceleration is less than a certain threshold in the first 10 minutes starting from the current time. For this embodiment, these driving information data can be used to characterize driving smoothness, driving style, etc. in the past period of time.

Vehicle status information includes: current passenger occupancy status and rear seat occupancy status. For example, at the current moment, the co-pilot occupancy status is 1, which means there is someone, and the occupancy status of the co-pilot is 0, which means there is no one. At the current moment, the rear seat occupancy status is 1, which means there is someone in it, and the occupancy status is 0, which means there is no one. For this embodiment, the vehicle status information can be used to distinguish whether the user is driving alone. If there is someone in the co-pilot, such as a child, it may be easier to select children's songs.

The vehicle location information includes: the driving position trajectory within the target distance before the current time and the starting point of the current trip. For example, the driving position trajectory within the target distance before the current time can be the Global Positioning System (GPS) position sequence of the past 1 kilometer starting from the current time, and the interval can be 100 meters. For this embodiment, the vehicle location information can indirectly reflect the road condition information, and then be used to represent the smoothness of driving in the past period, etc.

Vehicle environment information includes: current weather information, current wiper status, current interior temperature, and current interior humidity. For example, the current weather information may include: sunny, or cloudy, or light rain, or moderate rain, or heavy rain, or moderate snow, or blizzard, or haze and other weather types, as well as the wind level of outdoor weather. The current wiper status may include whether the wiper is currently on, the wiper gear, etc. For this embodiment, the vehicle environment information can be used to represent the user's physical comfort and mood affected by the weather, and can also indirectly reflect the driving environment information, and can also represent the smoothness of driving.

Step 202: Based on the current driving characteristics of the vehicle, obtain historical configuration information for different audio channels selected by the user in similar historical driving scenes.

For this embodiment, when the user needs to adjust the sound effects for in-car music playback while driving, the above-mentioned current driving characteristics can be used as a reference to obtain the history of different audio channels selected by the user in similar historical driving scenes. Configuration information is recommended.

Optionally, step 202 may specifically include: first calculating the similarity between the current driving characteristics of the vehicle and the corresponding sample driving characteristics when the user historically selected the audio channel configuration; and then obtaining the similarity greater than the target threshold (the target threshold can be determined according to actual needs Historical configuration information for different channels selected corresponding to the sample driving characteristics set in advance).

Among them, the sample driving characteristics include: time information, driving information, vehicle status information, vehicle location information and vehicle environment information of the user in the historical driving process. For the specific content of these characteristic information, please refer to the time information, driving information, The explanation of the vehicle status information, vehicle location information and vehicle environment information will not be repeated here. The sample driving characteristics can be the historical driving characteristics of the user in the historical driving process.

Through the above optional methods and through similarity calculation, the historical configuration information of different audio channels selected by the user in similar historical driving scenes can be found relatively accurately, thereby improving the accuracy of information recommendation.

For example, similarity calculation is performed between the vehicle's current driving characteristics and the sample driving characteristics corresponding to the user's historical selection of audio channel configuration. Specifically, it may include: separately calculating time information, driving information, vehicle status information, vehicle location information, and vehicle environment. The corresponding similarity of the information is then multiplied by the corresponding weight value (which can be preset according to the actual situation) and then summed to obtain the similarity between the vehicle's current driving characteristics and the sample driving characteristics.

For example, based on the five dimensional features of time information, driving information, vehicle status information, vehicle location information and vehicle environment information, the similarity between the current driving feature and the sample driving feature = time information similarity * time information weight value + driving information similarity * driving information weight value + vehicle status information similarity * vehicle status information weight value + vehicle location information similarity * vehicle location information weight value) + vehicle environment information similarity * vehicle environment information weight value. Among them, the similarity calculation for each dimensional feature of time information, driving information, vehicle status information, vehicle location information and vehicle environment information can be calculated using a similarity metric such as cosine distance or Euclidean distance.

Step 203: Recommend the obtained historical configuration information.

This embodiment can recommend the obtained historical configuration information, so that the user can configure different channels according to the area in the car based on the recommended historical configuration information, such as the mute configuration and/or gain corresponding to different channels. configuration, and/or delay configuration, etc. This can improve the efficiency of setting tuning parameters.

Step 204: Obtain the user's tuning configuration information for different channels based on the recommended historical configuration information.

These different channels can be channels in different areas of the car. In this embodiment, the user can choose whether to use the recommended tuning parameter setting information (ie, the recommended historical configuration information) according to his or her actual needs. If you do not choose to use the recommended tuning parameter setting information, users can set the tuning parameter configuration information for different channels by themselves.

Optionally, before obtaining the user's tuning configuration information for different channels, it may also include: responding to the configuration instructions of the crossover channels, configuring the crossover points corresponding to each area in the car, and obtaining each area according to its respective Multiple channels determined by corresponding crossover points. The crossover points may include: a crossover point between bass and midrange, and/or a crossover point between midrange and treble, etc.

In this embodiment, in addition to adjusting the mute configuration, gain configuration, and delay configuration of each channel, the user can also set the frequency crossover point of the channel. For example, by configuring the frequency crossover point corresponding to each area in the car, Then you can get left front door bass, left front door midrange, left front door treble, right front door bass, right front door midrange, right front door treble, etc., which can meet more tuning setting needs.

In order to improve the efficiency of tuning configuration, as an optional method, obtain the user's tuning configuration information for different channels, which may include: obtaining the combined tuning configuration information of multiple channels corresponding to the same area in the car, where , multiple channels corresponding to the same area can be adjusted with unified parameters.

For this embodiment, the user can set the channel merging instructions in advance, and the car terminal can respond to the channel merging configuration instructions to bind multiple channels corresponding to the same area in the car, so that the channels corresponding to the same area can be bound. Multiple channels can be adjusted with unified parameters. Later, the combined tuning configuration information of multiple channels corresponding to the same area in the car can be obtained. Alternatively, the car terminal can also pre-configure the channel merging and provide the pre-configured information to the user. When the user activates the channel merging option, the tuning configuration information received by the car terminal is for the channel. Merged configuration information.

For example, since there are crossover channels in the same area, if the user does not want to adjust each channel separately, multiple channels can be combined into one channel for adjustment. For example, if the front door has bass, midrange, and treble channels, you can Three channels are combined into one channel for parameter adjustment, and the crossover point can use default parameters.

As shown in Table 1, it is an exemplary channel merging combination:

Table 1

After the settings in Table 1 above, multiple channels corresponding to the same area can be adjusted with unified parameters, which improves the tuning configuration efficiency.

In order to improve the efficiency of tuning configuration, as another optional method, obtain the user's tuning configuration information for different channels. Specifically, it may also include: obtaining the tuning configuration information of multiple channel groups corresponding to the left and right symmetrical areas in the car. Sound configuration information, in which the multiple channels corresponding to the left and right symmetrical areas can be uniformly adjusted.

For this embodiment, the user can set the channel grouping instructions in advance, and the car end side can respond to the channel grouping configuration instructions to bind multiple channels corresponding to the left and right symmetrical areas in the car, so that the left and right Multiple channels corresponding to symmetrical areas can be adjusted uniformly. Alternatively, the car terminal can also pre-configure the channel grouping and provide the pre-configured information to the user. When the user activates the channel grouping option, the tuning configuration information received by the car terminal is for the channel. Group configuration information.

For example, since the left and right channels in the cockpit are completely symmetrical, the adjusted gain, delay, equalization, and crossover are mostly the same, such as the left front door bass and right front door bass channels, so the same gain, delay, etc. can be used. Timing, balance, etc. can be grouped and adjusted to provide users with greater flexibility and improve tuning configuration efficiency. Among them, the symmetrically groupable channels include: left front and right front door bass, left front and right front door midrange, left front and right front door treble, left rear and right rear door bass, left rear and right rear door midrange, left rear and right rear door treble, Left and right rear surround midrange, left and right rear surround treble, left front and right front 3D midrange, left front and right front 3D treble, left rear and right rear 3D midrange, left rear and right rear 3D treble, etc.

Further optionally, the channels after the channels are merged can also be grouped and adjusted symmetrically on the left and right. For example, the groups that can be grouped include: left front door and right front door channels, left rear door and right rear door channels, left surround and right surround channels, left front 3D and right front 3D channels, left rear 3D and right rear 3D channels, etc.

After the user sets the tuning parameters, it can also be shared online to share the tuning settings with other car owners. corresponding Optionally, the obtained tuning configuration information (the tuning configuration information in step 204) can also be uploaded and shared. This embodiment may also include: in response to the configuration sharing instruction, uploading the tuning configuration information to the cloud for authentication (such as Verify whether the sharing user is a community user, or whether the user has sharing permissions, etc.). Among them, the tuning configuration information after passing the authentication can be shared with the community. For example, parameters adjusted by users can be uploaded to the cloud for community sharing, and tuning parameters certified by the server can be recommended to users, forming a closed loop of tuning application ecology. Users can store the tuned parameters locally, or choose to upload them to the cloud for community sharing. As shown in Figure 4, they are uploaded to the cloud (or can be called the server) through the 5G communication system. The cloud can be stored, authenticated and downloaded. After the OEM downloads and verifies the user's tuning, it will be officially certified and pushed. All users can download and save the pushed content locally and apply the sound effects to their own cars. Media playback can be processed through the downloaded sound effect parameters. , forming a tuning application ecosystem.

Compared with the current traditional user-defined equalizer adjustment parameters that can only be stored locally and cannot be uploaded to the cloud and shared with other car owners, the solution provided by this embodiment allows user tuning parameters to be uploaded to the cloud for community sharing, thereby obtaining After the OEM certification, other users can download the parameters and apply them, forming an ecological closed loop of tuning applications. Tuning is no longer only done locally. Users can interact with each other to tune. Based on the data shared by the cloud community, each user can become a tuner. All cloud community certified parameters can be downloaded at will, which is rich. User choice increases interaction and playability, improving user experience.

Step 205: Perform digital signal tuning processing on the media stream by calling the control interface based on the sound effect parameter values corresponding to the tuning configuration information of different channels in the sound effect algorithm library.

Among them, the media stream after tuning processing can be used for sound playback.

This embodiment proposes a control scheme that considers multi-channel sound playback in different areas in the car. By opening a more channel tuning interface to the user, the user's degree of freedom in tuning is greatly improved, and the entire tuning can be customized. For car sound effects, by applying the technical solution of this embodiment, the user can control the muting of any channel during car music playback and adjust the sound quality, sound field and sound image of the entire car.

Further, in order to illustrate the specific implementation process of the example shown in Figure 4 above, that is, in order to improve the current existing technology, user-defined tuning parameters for sound effects can only be stored locally in the user's local area, and other users cannot directly obtain the tuning parameters. , other users can only define the tuning parameters themselves, which is a time-consuming and labor-intensive technical issue. Combined with the contents of the above embodiments, this embodiment also provides a sound data processing method, which can be applied to the server (or cloud, etc.) side for execution. As shown in Figure 5, the method includes:

Step 301: The server receives the tuning configuration information of its different channels sent by the client.

The tuning configuration information of these different channels may include: mute configuration, gain configuration, delay configuration, etc. of each of these different channels.

In this embodiment, the user can choose whether to upload the tuning configuration information of different channels to the server according to actual needs. If the user chooses to upload for sharing, the server will receive the tuning configuration information of different channels sent by the client.

Step 302: The server authenticates the tuning configuration information.

In order to ensure that the tuning configuration information shared with other users is safe, reliable, and true and valid information, it is necessary to Tuning configuration information for authentication. For example, verify whether the user sharing is a community user, or whether the user has sharing permissions, etc. If the user is not a community user and the user does not have sharing permissions, it can be directly determined that the authentication fails (that is, the authentication fails).

For example, first, the blacklist and the whitelist can be used for filtering. If the account ID of the client with the above tuning configuration information does not exist in the blacklist, and/or the client ID exists in the whitelist, the tuning configuration information can be further filtered. If the account ID of the client with the above-mentioned tuning configuration information exists in the blacklist, it can be directly determined that the authentication fails (that is, the authentication fails).

Step 303: If the tuning configuration information passes the authentication, the server marks the tuning configuration information as having passed the authentication.

Among them, the tuning configuration information with the authentication mark can be shared with other clients.

In this embodiment, there are many optional ways of marking, such as adding a specific authentication label to the tuning configuration information that has passed the authentication, and the tuning configuration information with this authentication tag can be shared with other clients; Another example is to mark the tuning configuration information that has passed the certification as certified, and mark the tuning configuration information that has not passed the certification as not certified. When sharing, only share the tuning configuration information marked as certified, etc.

By applying the technical solution of this embodiment, user-defined tuning configuration parameters can be uploaded to the server for sharing. After obtaining authentication, other users can download the parameters and apply them, forming an ecological closed loop of tuning applications. Tuning is no longer only performed locally, users can interact with each other to tune, so that users can obtain the tuning configurations shared by other users for direct use, saving time and effort. Based on the shared data, each user can become a tuner, and all server-certified tuning configuration parameters can be downloaded at will, enriching user choices, increasing interaction and playability, and improving user experience.

Further, as a refinement and expansion of the above embodiment, there may be multiple optional methods for the specific authentication process in step 302. As an optional method, step 302 may specifically include: first obtaining the exchanged information according to the set evaluation dimensions. scoring information of the tuning configuration information; and then based on these scoring information, it is determined whether the tuning configuration information is authenticated.

This set evaluation dimension can have multiple evaluation dimensions according to the acoustic requirements, and then each evaluation dimension will get corresponding scoring information. Then, through the scoring information of these evaluation dimensions, it can be comprehensively judged whether the specific content of the tuning configuration information has passed the certification. . Through this optional method, the tuning configuration information can be accurately authenticated, ensuring that the authenticated tuning configuration information is safe, reliable, and true and effective.

For example, obtaining the scoring information of the tuning configuration information according to the set evaluation dimensions may include: first using the tuning configuration information to play test songs (corresponding test songs can be specified for different evaluation dimensions); and then based on the test The playback effect of the song is obtained by scoring according to the set evaluation dimensions. The set evaluation dimensions can include at least one of: sound quality dimension, sound field dimension, sound image dimension, overall listening dimension, panoramic sound dimension, and vibration dimension. ;

Correspondingly, based on these scoring information, determine whether the tuning configuration information is authenticated, which may include: performing a weighted summation of the scoring scores of the set evaluation dimensions to obtain a total evaluation score; if the total evaluation score is greater than or equal to the target score threshold ( It can be preset according to actual needs, such as 60 points or 80 points, etc.), then it is determined that the tuning configuration information has been authenticated.

The sound quality dimension can be divided into sub-dimensions such as low frequency, medium frequency, high frequency, and balance. Measurement for low-frequency sub-dimensions For example, based on the tuning configuration information, when playing song 1 (a song used to reflect low-frequency effects), the electronic drum beats of the first 30 seconds are obtained for evaluation. The evaluation is expected to be thick and full, elastic, clean and clear, and with natural envelope. For the test of the mid-frequency sub-dimension, for example, playing Song 2 (a song used to reflect the mid-frequency effect) based on the tuning configuration information for evaluation, the evaluation expectation is that the human voice is rich and full, soft, warm, and clear; the fundamental frequency of the guitar is full, and the strings are consistent with The cabinet resonates naturally and has charm. For the test of the high-frequency sub-dimension, for example, playing Song 3 (a song used to reflect the high-frequency effect) based on the tuning configuration information for evaluation, the evaluation is expected to be that the maracas are delicate and real, the guitar is crisp and not dull, and the vocals have natural labial and dental sounds. Clear, realistic and detailed. For the test of the balance sub-dimension, for example, playing song 4 (a song used to reflect the balance effect) based on the tuning configuration information for evaluation, the evaluation is expected to be that the three sections perform their own duties, low-frequency drum beats, rich instruments, and delicate The human voice can be displayed without being overshadowed.

The dimensions of the sound field can be divided into sub-dimensions such as width, height, depth, left-right symmetry, and resonance. For the test of the width sub-dimension, for example, song 5 (a song used to reflect the width effect) is played based on the tuning configuration information for evaluation. The evaluation is expected to have a strong three-dimensional effect on the left and right sides of the intro, and the sound field will be the same width as the door panels on both sides. For tests on the height sub-dimension, for example, song 6 (a song used to reflect the height effect) is played based on the tuning configuration information for evaluation. The evaluation is expected to be that the low frequency is above the IP platform, and the human voice and musical instruments are realized directly in front of each passenger. For the test of the depth sub-dimension, for example, playing song 7 (a song used to reflect the depth effect) based on the tuning configuration information for evaluation, the evaluation is expected to be that the vocal position of the front row is deep in the front windshield, and the rear row is in the front seat. At the headrest of the chair, avoid being too close to passengers to create a sense of oppression. For tests on the left-right symmetry sub-dimension, for example, song 8 (a song used to reflect the left-right symmetry effect) is played based on the tuning configuration information for evaluation. The evaluation is expected to have the same listening experience for the passenger sitting on the left side and the same listening experience for the passenger sitting on the right side. . For the test of the resonator dimension, for example, song 9 (a song used to reflect the resonance effect) is played based on the tuning configuration information for evaluation. The evaluation expectation is that there will be no obvious resonance noise in the first 30 seconds.

The sound and image dimensions can be divided into sub-dimensions such as position and focus. For the test of the position sub-dimension, for example, song 10 (a song used to reflect the position effect) is played based on the tuning configuration information for evaluation, where the evaluation expectation is that the human voice is located directly in front of each passenger. For the test of the focus sub-dimension, for example, song 11 (a song used to reflect the focus effect) is played based on the tuning configuration information for evaluation. The evaluation expectation is that the vocal focus is emitted from an area as large as a fist and does not diverge.

The overall listening dimension can be divided into sub-dimensions such as bandwidth, dynamic range, surround feeling, layering, clarity, volume curve, equal loudness compensation, and speed compensation. The dimensions of panoramic sound can be divided into sub-dimensions such as orientation, surround, spatial width, clarity, and bass compensation.

In this embodiment, each sub-dimension is scored separately, that is, it is judged whether it meets the expected evaluation standard. The closer the score is, the higher the score is. Finally, the scoring score corresponding to each sub-dimension can be obtained, and then the scoring score corresponding to each sub-dimension is multiplied. With their corresponding weights (for example, the weight of the low-frequency sub-dimension of the sound quality dimension is 4, the weight of the position sub-dimension of the audio-visual dimension is 8, the weight of the orientation sub-dimension of the panoramic sound dimension is 6, etc.), and then the sum is obtained. point. If the total score is greater than or equal to the target score threshold, it may be determined that the tuning configuration information has passed the authentication, and if the total score is less than the target score threshold, it may be determined that the tuning configuration information has not passed the authentication. It should be noted that in practical applications, the total score can also be calculated by multiplying the total score by a scaling factor or adding or subtracting a constant, etc., to obtain the final total score. Judgment etc.

In a specific application, the user can also obtain tuning configuration information for different channels for a specific song setting, and then obtain tuning configuration information corresponding to the song. Therefore, optionally, step 301 may specifically include: the server receives tuning configuration information for different channels it has and a target song corresponding to the tuning configuration information sent by the client. Accordingly, the above-mentioned use of the tuning configuration information to play a test song may specifically include: using the tuning configuration information to play the target song; accordingly, the above-mentioned acquisition of a scoring score according to a set evaluation dimension based on the playback effect of the test song may specifically include: based on the playback effect of the target song, acquisition of a scoring score according to a set evaluation dimension.

For example, when a user is listening to a certain song, he sets the tuning configuration information of each channel that he thinks is good for the song, and uploads it to the server for sharing. The server can use this information when authenticating the song. The song is used as a test song to test the playback effect of the tuning configuration information. The specific process is similar to the test process of each evaluation dimension mentioned above. The difference is that this song is used uniformly as the test song. If the final total score obtained is greater than or equal to a certain threshold, it can be indicated that the tuning configuration information has passed the authentication and is the tuning configuration information set for the song.

Through this optional method, the tuning configuration information of the target song can be accurately authenticated, which not only improves the efficiency of authentication, but also meets more business needs.

Further optionally, if the tuning configuration information of the target song is authenticated, the method of this embodiment may further include: combining the tuning configuration information with the target song to generate binding recommendation information. That is, when recommending to other users, the tuning configuration information is recommended together with the target song.

For example, when other users are listening to this song (target song), a pop-up prompt will appear that they can use the matching tuning configuration information. They do not need to set the tuning parameters themselves, and can directly use the already set tuning configuration information to play the song. Or when other users need to listen to songs, they can choose the recommendation mode, and then the server recommends the song (target song) that the user can listen to, and uses the matching tuning configuration information. When the user selects the song to play, it will automatically match the song. Use this tuning configuration information.

Through the above optional method, the user's listening experience can be improved, and the tuning parameters of the target song can be shared, which can meet more business needs and increase the user's degree of freedom.

For the specific authentication process in step 302, as another optional method, step 302 may specifically include: testing the frequency response and phase of the tuning configuration information; if the frequency response and phase information corresponding to the tuning configuration information meet the target If the change pattern is found, it is determined that the tuning configuration information has been authenticated. Through this optional method, the tuning configuration information can be accurately authenticated, ensuring that the authenticated tuning configuration information is safe, reliable, true and valid.

For example, the frequency response fluctuation curve and phase fluctuation curve corresponding to the tuning configuration information can be obtained. If the frequency response fluctuation curve and the phase fluctuation curve both comply with the target change law, it can be determined that the tuning configuration information has been authenticated, otherwise it can be determined that the tuning configuration information has been authenticated. The configuration information failed to pass authentication.

For the specific authentication process in step 302, as another optional method, the above two optional methods can be combined to comprehensively determine whether the tuning configuration information has passed the authentication. For example, obtain the scoring information of the tuning configuration information according to the set evaluation dimensions, and test the frequency response and phase of the tuning configuration information; then based on this scoring information, and the test results of the frequency response and phase of the tuning configuration information, Comprehensively determine whether the tuning configuration information is authenticated. If each If the total score of the evaluation dimension is greater than or equal to a certain score threshold, and the frequency response and phase information corresponding to the tuning configuration information conform to the target change pattern, it is determined that the tuning configuration information has been authenticated.

Through the above optional methods, it can be comprehensively judged from multiple perspectives whether the tuning configuration information has passed the authentication, ensuring that the tuning configuration information that has passed the authentication is safe, reliable, true and effective information.

Further optionally, the method of this embodiment may also include: generating recommendation information based on the tuning configuration information with a certification mark and sending it to the client, such that the generated recommendation information can be presented to the user in a table form, and the user can select the tuning configuration information in the table according to their own needs, and can also list the author information of setting the tuning configuration information and corresponding user evaluation information in the table.

Through this recommendation method, users can intuitively understand which shared tuning configuration information can be used, and can interact with other users for tuning, which improves the user experience.

The content of the above embodiment is the sound data processing process described on the server side. Furthermore, in order to fully explain the implementation of this embodiment, this embodiment also provides a sound data processing method applied to the client side. , it should be noted that this method can be combined with the method shown in Figure 5 above. As shown in Figure 6, the method includes:

Step 401: The client obtains the tuning configuration information of different channels it has.

For example, after the user agrees, the tuning configuration information set by the user can be shared, that is, the process shown in steps 401 to 402 is performed.

Step 402: The client sends the tuning configuration information to the server.

Further, the server is allowed to authenticate the tuning configuration information (for the specific authentication process, please refer to the example description in Figure 5 and will not be repeated here), where the tuning configuration information with the authentication mark can be used to be shared. to other clients.

By applying the solution of this embodiment, tuning is no longer only performed locally, and users can interact with each other for tuning. In this way, users can obtain tuning configurations shared by other users for direct use, saving time and effort. Based on the shared data, each user can become a tuner, and all server-certified tuning configuration parameters can be downloaded at will, enriching user choices, increasing interaction and playability, and improving user experience.

Further, as a refinement and expansion of the above embodiment, optionally, the different channels in step 401 can be channels in different areas in the car, different from the left channel and the right channel. In this optional embodiment, The tuning configuration information of different channels may include: mute configuration, gain configuration, delay configuration, etc. of each of these different channels.

For example, the in-vehicle area in this embodiment may be the area inside the vehicle's cockpit, and the different channels may be the channels of different areas in the cockpit, such as the center channel, left front door channel, right front door channel, left rear door channel, right rear door channel, left surround channel, right surround channel, left front 3D channel, right front 3D channel, left rear 3D channel, right rear 3D channel, etc.

The operation interface of the client's car system opens more tuning interfaces, which can specifically include: muting or unmuting each channel, etc., giving a higher degree of freedom in audio control; the gain setting of each channel can be set in one The gain can be adjusted arbitrarily within a range, and the settings can be reset to default values, etc., to finely define the sound quality that the user likes; the delay setting of each channel can be adjusted arbitrarily within a range, and can be reset. Restoring the settings to default values, etc., you can control the sound field and sound image of the entire vehicle, and adjust the width, depth or height of the sound field.

In practical applications, users can configure the corresponding mute information, and/or gain information, and / or delay information, etc., which can greatly increase the user's freedom in tuning. Multiple sound channels in different areas in the car can be set separately, and the vehicle sound effects can be customized based on the music playback environment of the area in the car. The sound effect parameter values are more suitable for car music playback. Compared with the current way of setting the left channel and right channel only through an equalizer, this embodiment can open the tuning interface of multiple channels in different areas in the car to the user, and can fully consider the different conditions in the car. Sound effect parameter settings for regional sound playback. Specifically, during car music playback, users can control the muting of any channel and adjust the sound quality, sound field and sound image of the entire car.

On this basis, users can also upload the tuning parameters set in their own cars to the cloud for sharing, so that other users (such as users driving the same car model) can download the tuning parameters shared by the user and then apply them directly Go to local vehicles to play music and quickly experience the music playback effect. Since these sound effect parameter values will be more suitable for in-car music playback, they can effectively improve the listening experience of users in the car.

Further, in order to meet the sharing needs of the specified user, optionally, step 402 may specifically include: sending the tuning configuration information and the target account identification to the server, so that after the server determines that the tuning configuration information is authenticated, it will The tuning configuration information is sent to other clients corresponding to the target account ID. Through this optional method, it is possible to share the tuning parameters set by designated users, meet more interaction needs between users, and improve the user experience.

In the DSP module, the sound effect parameter values corresponding to the current configuration information (mute configuration of different channels, and/or gain configuration, and/or delay configuration, etc.) in the sound effect algorithm library are obtained, and then based on the obtained sound effect parameters The value is to perform digital signal tuning processing on the accessed media stream, so that the media stream can be processed by a real-time tuning algorithm. Finally, the tuned media stream is emitted through a power amplifier and a speaker, and then the sound is played and perceived by the user.

After the user sets the tuning parameters, he or she can also share the tuning settings with other car owners over the Internet. Correspondingly, the obtained tuning configuration information can also be uploaded and shared. On the vehicle system side, in response to the configuration sharing instruction, the tuning configuration information is uploaded to the cloud for storage and certification. The tuning configuration information after passing the certification can be Sharing with the community means distributing. For example, parameters adjusted by users can be uploaded to the cloud for community sharing, and tuning parameters certified by the server can be recommended to users, forming a closed loop of tuning application ecology. Users can store the tuned parameters locally, or choose to upload them to the cloud for community sharing. As shown in Figure 4, they are uploaded to the cloud through the 5G communication system. The cloud can store and authenticate them, and push them after the authentication is passed. All users can download and save the content they push Locally, apply sound effects to your own car, and media playback can be processed through downloaded sound effect parameters to form a tuning application ecosystem.

Compared with the current traditional user-defined equalizer adjustment parameters that can only be stored locally and cannot be uploaded to the cloud and shared with other car owners, the solution provided by this embodiment allows user tuning parameters to be uploaded to the cloud for community sharing, thereby obtaining After the OEM certification, other users can download the parameters and apply them, forming an ecological closed loop of tuning applications. Tuning is no longer only done locally. Users can interact with each other to tune. Based on the data shared by the cloud community, each user can become a tuner.
